(The Hill) – Joe Biden’s office has complained to the Senate press gallery about a confrontation the vice president had with a conservative journalist last week on Capitol Hill.

Biden aides asked whether Senate rules were broken in the wake of the contentious exchange between the vice president and the reporter.

Jason Mattera, who works for Human Events, a conservative magazine, used a pretext to catch Biden off guard in a Senate hallway and grill him on claims the vice president has made about jobs legislation.

Biden’s office has also contacted the standing committee of correspondents, which oversees the gallery, regarding whether Mattera broke the rules by ambushing him.
